| Pharmacist | Medication Access | View prescriptions, dispense drugs |
| Administrative Staff | Financial/Data Entry Access | Manage billing, patient registration |
| Access Level | Security Risk | Data Integrity |
|---|---|---|
| No Control | 🔴 Very High | ❌ Unreliable |
| Basic Control | 🟡 Moderate | ⚠️ Partially Reliable |
| Role-Based Control (RBAC) | 🟢 Low | ✅ Highly Reliable |
Implementing proper access control is essential for maintaining the confidentiality, integrity, and security of patient data. By ensuring that each staff member only accesses what they need, hospitals can significantly reduce risks while maintaining efficient workflows.
Data encryption is a fundamental pillar of patient data security. It involves converting sensitive information into an unreadable format (ciphertext) that can only be accessed or decoded by authorized users with the correct decryption key.
Even if data is intercepted during transmission or accessed without permission, encryption ensures that it remains unusable and protected from exposure.
| 📄 Original Data | ➡️ | 🔐 Encryption Process | ➡️ | 🔒 Encrypted Data (Ciphertext) | ➡️ | 🔓 Decryption (Authorized Access) | ➡️ | 📄 Readable Data |
| Type | Description | Use Case |
|---|---|---|
| Data at Rest | Encryption of stored data in databases or servers | Protecting patient records saved in EMR systems |
| Data in Transit | Encryption during data transfer over networks | Securing communication between browser and server (HTTPS) |
| End-to-End Encryption | Data encrypted from sender to receiver without intermediate access | Secure sharing of patient reports |
| Security Factor | No Encryption | With Encryption |
|---|---|---|
| Data Readability | ❌ Easily readable | ✅ Unreadable without key |
| Breach Impact | 🔴 Severe | 🟢 Minimal |
